Quark Anti-Quark Fusion and Walking RG Flows

Filipp Chernikov, Nikolay Gromov, Amit Sever

We study the fusion of two conjugate conformal line defects on the sphere. At small separation, their spectrum is governed by a universal Fusion Master Equation. Below a critical c…

Short Strings in Three-Dimensional Anti-de Sitter Space: from Weak to Strong Coupling

Simon Ekhammar, Nikolay Gromov, Bogdan Stefański +1

We numerically solve the conjectured Quantum Spectral Curve for strings on AdSST with R--R charge from weak to strong coupling. At strong coupling, the spec…

Integrability and the spectrum of two-dimensional fishnet CFT

Simon Ekhammar, Nikolay Gromov, Fedor Levkovich-Maslyuk +1

We formulate a closed set of equations for the spectrum of two-dimensional bi-scalar fishnet conformal field theory, comprising Baxter equations and quantisation conditions, which…

Gluing Quantum Spectral Curves: A Two-Copy osp(4|2) Construction

Filipp Chernikov, Simon Ekhammar, Nikolay Gromov +1

We propose a Quantum Spectral Curve for planar string theory on AdS3*S3*S3*S1 supported by pure Ramond-Ramond flux. Our proposal is built on symmetry considerations and integrabili…

Regge Trajectories of N=4 SYM Part I: General Asymptotic Baxter-Bethe Ansatz

Simon Ekhammar, Nikolay Gromov, Michelangelo Preti

In this work, we derive a novel set of equations - the Asymptotic Baxter--Bethe Ansatz - that determine the asymptotic spectrum of Regge trajectories in the BFKL regime of N=4 SYM.…

Probing Line Defect CFT with Mixed-Correlator Bootstrability

Andrea Cavaglià, Nikolay Gromov, Julius Julius +2

We continue our study of the defect CFT on a Maldacena-Wilson line in N=4 Super-Yang-Mills theory using Bootstrability -- the conformal bootstrap supplemented with exact integrabil…

Demystifying the Massless Sector in AdS_3 Quantum Spectral Curve

Simon Ekhammar, Nikolay Gromov, Bogdan Stefański

We show that in the asymptotic large-volume limit, the original proposal for Quantum Spectral Curve for AdS3 x S3 x T4 with R-R flux has a wider class of solutions, than studied pr…

Long Range Asymptotic Baxter-Bethe Ansatz for N=4 BFKL

Simon Ekhammar, Nikolay Gromov, Michelangelo Preti

We demonstrate that the Balitsky-Fadin-Kuraev-Lipatov regime of maximally supersymmetric Yang-Mills theory can be explicitly solved up to the L+1 order in weak coupling by uncoveri…

New Approach to Strongly Coupled N = 4 SYM via Integrability

Simon Ekhammar, Nikolay Gromov, Paul Ryan

Finding a systematic expansion of the spectrum of free superstrings on AdSS, or equivalently strongly coupled N = 4 SYM in the planar limit, remains an outstandi…

Computing Four-Point Functions with Integrability, Bootstrap and Parity Symmetry

Andrea Cavaglià, Nikolay Gromov, Michelangelo Preti

The combination of integrability and crossing symmetry has proven to give tight non-perturbative bounds on some planar structure constants in =4 SYM, particularly in t…

Boundary Overlaps from Functional Separation of Variables

Simon Ekhammar, Nikolay Gromov, Paul Ryan

In this paper we show how the Functional Separation of Variables (FSoV) method can be applied to the problem of computing overlaps with integrable boundary states in integrable sys…

Quantum Fishchain in

Nikolay Gromov, Amit Sever

In our previous paper we derived the holographic dual of the planar fishnet CFT in four dimensions. The dual model becomes classical in the strongly coupled regime of the CFT and t…

Quantum Spectral Curve and Structure Constants in N=4 SYM: Cusps in the Ladder Limit

Andrea Cavaglià, Nikolay Gromov, Fedor Levkovich-Maslyuk

We find a massive simplification in the non-perturbative expression for the structure constant of Wilson lines with 3 cusps when expressed in terms of the key Quantum Spectral Curv…
